Given E and H, obviously you can calculate Poynting vector (N=ExH), but then how do you find the time average of N (N')?(adsbygoogle = window.adsbygoogle || []).push({});

(I won't write all the question I'm trying to answer here but basically I'm trying the verify an equation, the says N' = 0.5* Re{ F x I* } where F and I are fields such that E= Re{F} and H=Re{H}. So obviously I can't use that equation. How else can I find N'?
